MACHINE FOR ATTACHING SHANK-PIECES.

Specification of Letters Patent.

Application filed December 10, 1909. Serial No. 532,477.

To all whom it may concern:

Be it known that I, EDWIN F. MOWER, a citizen of the United States,resident of Boston, in the county of Suffolk and State of Massachusetts,have invented a new and useful Improvement in Machines for AttachingShank-Pieces, of which the following, taken in connection with theaccompanying drawings, is a specification.

My machine is especially adapted for attaching metallic shank-pieces tothe soles of boots and shoes, and consists of peculiar mechanism whichmay be best understood by reference to the complete specification.

The object of the invention is to make a machine that will be rapid andreliable in its action.

This object I attain by the mechanism shown in the accompanyingdrawings, in which- Figure 1 is a front elevation of the machinecomplete. Fig. 2 is a side elevation of the same except that one of theside plates is removed to show the interior parts more clearly, and thebelt wheel is omitted. Fig. 3 is a vertical section showing more clearlythe important working parts. Fig. 4 is a horizontal section taken online H of Fig. 1. Fig. 5 is a plan View of the shoe holder or rest, Fig.6 is a plan view of one of the metallic shank-pieces.

In the drawings A represents the base of itlhe machine, A the uprightpart and A the ead.

B is the shoe rest which is mounted upon a supporting rod B said rodbeing attached to a foot lever by which the said shoe rest may be raisedand lowered as desired.

B is an adjustable gage connected to the shoe rest and assists inplacing the boot or shoe in the exact place required during the workingof the machine.

The shank-piece which this machine is particularly designed to operateupon is shown in plan in Fig. 6; it is made of any suitable metal and isprovided with barbs K K see Figs. 3 and 6. The position that the shankpiece Kfoccupies on the machine, when ready to be applied to the sole,is shown in Fig. 2.

The operating mechanism may be described as follows. The shank-pieceholder L Figs. 2 and 3 is made with a holding start L, which engageswith the opening at K formed in the shank-piece in punching up the barbK Fig. 6; the other end of the shank-piece is held by the spring piecesA A which clamp it by its edges and hold it frictionally only so that itmay be readily removed after it is attached to the sole. The holder L isforked at one end so as to be guided by the fixed pin L Fig. 2. Theother end of the holder L is loosely held by the pin L in the slot atthe lower end of the bent lever L which is pivoted to pivot L A cam L onthe shaft I-I causes the lever L to operate in one direction and thespring L causes it to move in the other direction.

In order to make the barbs K K of the shank penetrate the sole moreeasily and certainly holes are made in the said sole; for this purpose Iuse the awls C and D. These awls are operated by the arms C and D whichare linked together by the link E; the arm D is pivoted to the head. Aby the screw pin D The arm 0 is rigidly attached to the rocker shaft Cby a screw nut C The said rocker shaft has an arm 0* attached to it by ascrew bolt C Fig. 1. The rocker arm 0 has a cam pin 0 constructed toengage with the cam groove C made in the face of the cam disk C Forstarting and stopping the machine a hand lever N is used; this leverworks through the rod N and a clutch device N of any desiredconstruction.

The lower edges of the side plates A A are shaped as shown in Fig. 2, soas to act in connection with the upper surface of the shoe holder B tocause the sole S to be forced temporarily to assume the contortionsshown in Fig. 3 to allow the awls and the barbs to penetrate the saidsole.

To operate this machine the user places a shank-piece K in position byhooking one end on to the holding start L and forcing the other end upbetween the springs A A now the shoe is placed on the holder B, then theholder is thrown up by a foot lever acting through the rod B this actionbrings the shoe up to the position shown in Fig. 3, the sole of the shoebeing forced up hard against the under side of the shank insertingmechanism and parts of the sole are bent up by the bosses B B as shown;now the operator starts the machine and the awls O and D puncture thesole and are drawn back and out; then the shank-piece holder U, by theaid of the holding start L,

draws the shank back forcing the barbs K K into the sole; the nextmovement is to send the holder L back, which releases the shank-pieceand the shoe holder B may be lowered and the shoe taken out with theshank-piece securely attached. And the machine is ready for anotheroperation.

What I claim is- 1. In a shank-piece attaching machine, a shank pieceholding device comprising a shank piece holder having a startconstructed to engage with one of the barb holes of the said piece,thereby holding the rear end of said shank piece, springs constructed tofrictionally hold the front end of said shank piece; and means foroperating said shank piece holder substantially as and for the purposeset forth.

2. In a shank-piece attaching machine, a shoe holding mechanismcomprising a lower holder constructed to hold the shoe from theunderside and having cross bosses which form a part of the surface ofthe holder upon which the outer side of the sole rests,

a guard-gage attached to the said holder constructed to assist inplacing the shoe in position; means for raising and lowering saidholder; fixed side plates attached to the head part of the machinehaving their lower edges shaped to conform to the upper surface of thesaid holder whereby the upward movement of the shoe holder clamps thesole, to which the shank piece is to be attached, between the saidholder and the lower edges of said side plates thereby molding the soleand forming ridges, awls for making holes in said ridges through whichholes the barbs of the shank-pleces are forced as and for the purposeset forth.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnesses, on this 29th day of November A.D. 1909.
